5. what are the major steps that occur during photosynthesis? what happens in each step (summarize briefly the key point(s))?
Photosynthesis is a complex process that can be summarized in two key steps: the light-dependent reactions and the light-independent reactions (also known as the Calvin cycle).
In the light-dependent reactions, light energy is converted into chemical energy in the form of ATP and NADPH. In the light-independent reactions, ATP and NADPH are used to convert carbon dioxide into glucose.
During the light-dependent reactions, light energy is absorbed by chlorophyll and other pigments in the chloroplasts of plant cells. This energy is used to split water molecules, releasing oxygen as a byproduct.
The energy from the absorbed light is then used to convert ADP (adenosine diphosphate) into ATP (adenosine triphosphate) and NADP+ (nicotinamide adenine dinucleotide phosphate) into NADPH. These energy-rich molecules, ATP and NADPH, are essential for the next step.
In the light-independent reactions, also known as the Calvin cycle, carbon dioxide enters the chloroplasts and combines with a five-carbon compound called RuBP (ribulose-1,5-bisphosphate). This process is facilitated by the enzyme RuBisCO (ribulose-1,5-bisphosphate carboxylase/oxygenase).
The resulting unstable six-carbon molecule quickly breaks down into two molecules of a three-carbon compound called PGA (phosphoglycerate). ATP and NADPH from the light-dependent reactions provide the energy and reducing power to convert PGA into PGAL(phosphoglyceraldehyde) through a series of enzymatic steps. Some PGAL molecules are then used to regenerate RuBP, while others combine to form glucose and other organic compounds.
Overall, photosynthesis is a remarkable process where plants capture light energy and convert it into chemical energy in the form of glucose, which serves as a fundamental energy source for both plants and other organisms in the food chain.

Explanation:
cells lose water when placed in a __________ solution.
Cells lose water when placed in a hypertonic solution.
When a cell is placed in a hypertonic solution, it means that the concentration of solutes in the solution is higher than the concentration of solutes inside the cell. As a result, water molecules tend to move out of the cell in an attempt to equalize the solute concentrations on both sides of the cell membrane.
The process of water moving out of the cell in response to a hypertonic solution is known as osmosis. Since there is a higher solute concentration outside the cell, water molecules diffuse from an area of lower solute concentration (inside the cell) to an area of higher solute concentration (outside the cell).
As water leaves the cell, it causes the cell to shrink or undergo cellular dehydration. This can have detrimental effects on cellular structure and function. In extreme cases, excessive water loss can lead to cell damage or even cell death.
Therefore, when a cell is placed in a hypertonic solution, it loses water due to the osmotic movement of water molecules out of the cell.

some scientists believe that if __________ could be lengthened, age-related problems could be slowed.
Answer:
Telomeres
Explanation:
Telomeres are present at the ends of chromosomes and prevent the lose of genes. They shorten as a person ages. Thus lengthening them may slow down age related problem.
If telomeres could be lengthened, the age-related problems could be slowed.
• The end of a chromosome is known as a telomere it is formed of repetitive sequences of non-coding DNA, which protect the chromosome from destruction.
• With each cell division, shortening of telomere takes place. Eventually, with too much shortening of telomere the cell fails to divide any further.
• It is seen that with age shortening of telomere takes place.
• The continuous shortening of telomere results in apoptosis, senescence, thus, influencing the lifespan and health of a person.
• Shorter telomeres have been related to poor survival and increased incidence of diseases.
• It is believed that if the lengths of the telomeres can be increased than the age-related issues could become slow.
• However, the shortening of telomere can be increased or decreased by some of the lifestyle factors.
• Activities and better choice of diet possesses great tendency to diminish the rate of telomere shortening.
Thus, the given blank can be filled with telomeres.

B. Sleet is a combination of rain and snow.
C. The rain turned to sleet and snow later that afternoon.
D. Rain, snow and sleet are common during the month of December.
Answer:
C
Explanation:
Because it makes more sence
Frozen raindrops that hit the earth's surface are known as sleet (Ice Pellets). When sleet first forms, snow will be the precipitation that falls upwards. Thus, option C is correct.
What weather forecast rain, snow, and sleet are expected?Both sleet and freezing rain develop using the same fundamental mechanism: liquid droplets in a layer of warm air above the surface descend into a layer of freezing air close to the ground.
When snowflakes fall through a thin layer of warm air, they only partially melt, resulting in sleet.
These slushy drops then refreeze as they fall through a thick layer of icy air above the surface, and when they finally make it to the ground, they do so as frozen raindrops that bounce as they hit the ground.
When rain falls through a chilly layer and directly on the ground, it freezes on contact and forms a layer of ice. This is known as freezing rain.
Therefore, Snow that falls from a cloud and melts as it passes through an upper layer before falling back through a lower layer below freezing is known as sleet.
